The Problem with Christians

[Angrboda]

The KJV is inaccurate. Do a survey of the most reliable translations eg the ESV,  NAS or ISV and you won't find any mention of "sweet influences." What you get is either "bind the chains" or "bind the cluster."

Moot point as it turns out your source was wrong about them being 'bound' to begin with.

In Greek mythology, the Pleiades were seven sisters who were roaming free.  One binds that which is free, and loosens that which binds.  The verse is simply consistent with the metaphor which described each phenomena.  They no more knew that the belt of Orion were free stars than that they knew the Pleiades were maidens.  

The Book of Job is considered to be one of the oldest books in the Bible, if not the oldest. It most likely predates the Greek mythology.

The story* in the book of Job is likely one of the oldest in the bible, but it was likely put into writing sometime between the 7th and 5th centuries BCE, thus giving the right time frame for such an anachronism to enter the text.

"The earliest European references are somewhat later, in a poem by Hesiod in about 1000 BC and in Homer's Odyssey and Iliad."
